Abstract: A centrifugal debris separator for removing debris from a gas turbine engine fuel system comprises a debris separator inlet, a debris separator outlet and a separating chamber with a centerline extending in an axial direction and defined by an outer wall formed around the centerline. The separating chamber comprises a separating chamber inlet for receiving fluid, a first separator outlet to the separating chamber, a second separator outlet to the separating chamber provided to the outer wall of the separating chamber and a third separator outlet to the separating chamber defined by a third separator outlet wall formed around the centerline of the separating chamber. The debris separator inlet is fluidly connected to the separating chamber inlet. The debris separator outlet is fluidly connected to the first separator outlet.
